Quick question.
Whats the Max range/up compression can you run on any ECU (P73 in question here) before you'll need a new ECU/Tune?
Example:
B18C5
- Stock Comp = 10.6:1
- P73-A0X Tuned for 10.6:1
Now how far can I push the compression before a Stock P73-A0X won't be able to properly run the motor. I.E. Detonate because of too high comp.
Would a 10.87:1 from say a BC 2-Layer HG be OK to run with the Stock ECU?
Main reason I ask is I'd like to keep OBD2 Function, of course running a Chipped OBD1 ECU won't work that way.
